I have an electron based remote sensor that includes a BME280 for temperature and humidity. On occasion, the temperature will “stick” at either a very high (well over 100 degrees F) or very low (well below -100 degrees F). Resetting the system via my particle function soft reset will cause the sensor to hold at 32 degrees F, but ultimately doesn’t solve the problem. Manually disconnecting the battery and solar for a hard reset does solve the problem, but requires driving to the sensor. I am wondering if someone has made a circuit to disconnect all power from the particle to hard reset remotely.
From what I understand about watchdog circuits, they still do not provide a full power cutoff.
I have not been able to diagnose the problem with the BME280 (several units displaying this problem) and have been trying to work with Bosch to come up with a solution. If you have any suggestions about why the BME280 may be sticking, that would also be very helpful!
Thank you in advance.
